I've just notice this on my web site. They are testing new ad format or something is very buggy with their ads.
I like it, it looks promising. Espically if you have a leaderboard on the top of your page. They kind of look like a navigation under the ads.
It does look nice, only downside I can see if that's an integration of their "ad units" as users have 2 click on the search term... then a "sponsored" listing to get paid....
hey guys pls check it out the red circle with "this site accepts google checkout"....what that support to mean?
hmm.. I got them too in one of my site. and reuben0207, that means, you can pay via google checkout if you buy anything from that site.
